Log:

New tests for squareroot, coordinate with Cowlishaw,
maybe he'll keep this as a separated file or integrate
these tests in the standard squareroot.decTest file in
a later version. Thanks to Mark Dickinson.

+-- Special thanks to Mark Dickinson for tests in the range 1000-1999.
+--
+-- Extra tests for the square root function, dealing with a variety of
+-- corner cases.  In particular, these tests concentrate on
+--   (1) cases where the input precision exceeds the context precision, and
+--   (2) cases where the input exponent is outside the current context,
+--       and in particular when the result is subnormal
+--
+-- maxexponent and minexponent are set to 9 and -9 throughout these
+-- cases; only the precision changes.  The rounding also does not
+-- change, and should be irrelevant.  Ideally these tests could be
+-- run with all rounding modes to check that the rounding mode does
+-- not affect any of the results.
